Video is jittery or field reversal
on May 27, 2011 at 1:37:19 am

I am not sure how to ask this question. I am editing in an SD DV NTSC timeline. I have jpegs, footage from DVDs, footage from youtube. All is lower field and I am told that on tube TVs my images are shaking a bit. On my monitor (TV monitor) it looks fine. I added flicker filter and de-interlace and I am told I need to make the whole project progressive. My final out put is mini DV. What am I missing here? How can I make my video so it is not jittery or make it progressive?

If all is well, material on YouTube is de-interlaced.
That means that your 'normal' video runs at 60 FIELDS a second,
but the YouTube stuff runs at 30 FRAMES a second.
(as there is no time difference between the fields due to the de-interlacing)
That makes a bit of a 'strobe' look, but not 'jittery'

So, you don't have to do any de-interlacing / flicker fixing, unless the YouTube uploader made a mistake.
But since the video is scaled when uploading to YouTube, there is no way you can fix interlacing artefacts, as the fields are no longer one line high.
